"Here let me try." Steve sighed and crawled up on the bed beside her. "Go on, get out of my way. Go get a shot." He said, shoving her lightly. She fell to her side, laughing as she grabbed at his arm, trying to catch herself. "Hey! I'm trying to help you." He laughed, catching himself from falling with her.
"You started it. Now get my phone or I'll kick your ass." She laughed again, pushing herself up and swinging her feet so she could hop off the bed. She took a deep swig then plopped back down on the bed just as Steve sat up, holding her phone out triumphantly.
"Ta da!" He said.
"Yay" She squealed, snatching it from his hand before throwing her arms around him in a big hug. He hugged her back quickly before pushing her away from him. She fell back on the bed, phone in one hand and bottle of booze in the other. He yanked the bottle from her hand, unscrewed the top and took a big drink.
Steve screwed the top back on the bottle as he sat himself down, back against the wall again, center of the bed, legs dangling off the other side. Shelly made herself comfortable, propping herself up on his pillows, she relaxed back then kicked her legs out over her brother's lap again.
They sat that way for a long time, passing the bottle back and forth and talking about their plans for the year to come while he would be gone and she would be applying to colleges herself. Shelly and Steve both had a strong buzz going by the time the bottles were both empty. It went quicker than they had realized.
Shelly held the second bottle upside down "All out" She said sullenly.
"That's okay. I'm buzzing hard."
"Yeah but I'm enjoying our time together. I don't want it to end."
"Who said it has to? You can hang out longer." Steve patted her leg again.
"Aren't you tired?"
"Yes, aren't you?"
"Not really. You're just lame." She giggled
"I am not! I could hang out all night!" For a moment the realization that his little sister's bare bottom was pushed against his bare thigh hit him but he didn't want to say anything, he pushed it out of his mind, trying to ignore it. She made it hard to ignore as she wiggled against him.
Suddenly Shelly sat up. She bounced over him, straddling him and pinching his inner arm where it was most sensitive, just like she always did when they wrestled around. He told her more than once that was cheating because she knew how much it hurt. His hands shot back, trying to pinch her back and push her away at the same time. She bounced up and down on his lap, laughing and still trying to get the one up on him. He pinched the side of her breast and she squealed before pushing herself against him to hold him down.
Her huge breasts pushed into his face. He fought for the upper hand, trying to regain some control of the situation. He wrapped his arms around her, scooping up her bottom and lifting her off him. His fingers found her bare flesh, her soft, warm folds as his fingertips sunk between her butt cheeks. He easily lifted her just enough so he could turn, dropping her off to the side and falling with her. She landed on her back with him on top of her. Her legs wrapped around his body, desperately searching for a way to fight him off. She was laughing too hard to focus as his relentless attack began. He laughed right along with her, they struggled together, each fighting for control as they jabbed fingers at each other's sensitive skin.
Shelly twisted and turned, thrusting her hips up and down, side to side. Steve kept her pinned as tightly as he could to the bed. Shelly gasped for air between fits of laughter "Let me breathe!" she squealed as she turned her body, causing her too tight shirt to roll up over her breasts. Steve pretended not to notice, he was still laughing and was now tickling her underarm as he tried to ignore the raging boner that pressed against her wiggling ass.
She thrust her hips, hoping to throw him off balance but he was prepared for her movements and thrust back, keeping her pinned in place. Her large, round breasts jiggled and bounced as they laughed and played. Steve paid no attention to how hard he'd gotten and ignored the excitement that was building inside him from the feeling of his hardened cock pushing against his sister's soft pussy lips through his boxers. Another firm twist from Shelly's torso was met by a twist and thrust of his hips. His cock rubbed between them and finally sprang from the hole in his boxers, freeing itself as if of its own accord.
Shelly felt it too, felt her brother's hard prick and her own bubbling excitement in her body. Her mind didn't react, her body, her excitement and desire consumed her. She was no longer battling to win or gain control. Her hips took control and seemed to move intentionally to bring him closer to her entrance. She bounced and twisted, feeling him spring free from his boxers. She lifted and shifted downward and felt his cock trying desperately to push into her. Her mind ignored what was going on near their groins, instead choosing to focus on the fun they were having. She continued to laugh and so did he. He tickled her relentlessly, his hand brushing against her bare breasts each time he moved. She fought back, pinching at his underarm and trying to knock his support arm out from under him. Both of them played along, neither wanting to admit how turned on they'd both become.
The stiff head of his cock pushed between her warm, soft folds, it pressed into the firm area above her opening. It slipped out again as they moved, then back in, hitting nearer the hole this time. Her hips lowered, angled upward slightly then pushed up again to meet his thrust down. The head slipped into place, nearly entering her but not making it past his tip. Their hips stayed close together now, slower, smaller movements allowed his prick to slowly push deeper inside her. Her laughs became sprinkled with squeals of delight. The deeper he got into her, the more her laughter turned to moans. His fingers slowed their tickling motion as he slowly shifted his hand away from her armpit toward the side of her ample breast. He was fully inside her before he stopped tickling her and they were moving in unison, thrusting toward each other.
Steve's brain began to partially register what was happening as he realized how dangerously close he already was to cumming. His cock throbbed as his hips thrust it deep inside his sister. His hand, no longer tickling his sister now, moved from the side of her breast to the bottom where he scooped it into a cup and squeezed gently. Shelly quit battling him completely as pleasure took over her body and mind. Her arms rested above her head and her hips thrust, accepting her brother inside her as her pussy tightened around him, preparing for orgasm. She moaned her pleasure at his hand squeezing her massive breast and his cock sliding into her. Quickly their movements became more fluid, more intense and more secure as they both found the pleasure overwhelming, building quickly toward orgasm.
Steve built up speed until he pounded into her feverishly as she moaned. His sister's soft, velvety walls hugged his dick tightly, sucking him deeper into her wet heat. Shelly felt his body shudder, his cock throbbed inside her. She could feel every vein, every ripple as he slammed into her, massaging her inner walls with his lengthy shaft. He throbbed again and his body stiffened, suddenly she was being filled with his hot load as it shot deep inside her. She pushed up, grinding herself on him, breaking the edge of her own orgasm as he finished his. She panted out moans of delight as her orgasm raged through her body.
Her back arched off the bed as Steve, though spent, realized she was still cumming and pushed into as hard as he could manage. As her orgasm subsided, her body relaxed and Steve followed her lead. He let his body go limp, laying his head on her soft, bare breasts and trying to catch his breath. She felt his penis softening inside her and felt the small pop as he shrunk down and fell out of her. His cum leaked out of her and down her butt, creating a wet spot on the sheets under her. Neither moved, neither spoke. They breathed heavily, chests expanding largely as they tried to catch their breath together. Inside his brain, Steve heard the repeating question "What just happened?" but he pushed it back, trying to ignore it as his body descended from the height of passion.
Steve heard it first and reacted just as Shelly's mind began to register the sound of footsteps coming from the upstairs. They were moving quickly through the second level hallway, coming from their parent's bedroom and heading toward the stairway. Steve jumped up to his feet and tucked his penis inside his boxers before pulling the flap closed again. Shelly sat up, tugging her shirt down to cover her breasts then reaching for the empty bottles on Steve's night stand. She stood and shoved the bottles under his mattress. Steve tossed Shelly the blanket from his bed. "Here cover up." He said then rushed to his closet shelf where he grabbed a second blanket and wrapped it around his body. The last thing he grabbed was a deck of cards from his dresser. He dropped to his floor, sitting with the cards held in front of him. Shelly followed suit, he handed her some cards off the top of the deck and took a few for himself.
Shelly laughed loudly in her very best fake laugh as she desperately tried to pretend she wasn't out of breath and leaking a mixture of her own and her brother's cum onto his carpet just as Steve's bedroom door flung open. "What the hell is going on in here?" Their mother stood in the doorway, fuming and looking angry with a hint of confusion.
"Sorry, Mom. Shell and I couldn't sleep so we decided to play some cards. I think this move next week has us both a little anxious." Steve said sweetly as he turned to look at their red-faced mom.
"It sounded like... Well I thought someone... " She trailed off for a moment, not wanting to say what she had actually thought she'd heard. "Just get to bed. Both of you! You're being so loud down here you woke both me and your Dad." She said in a huff. "Now!" She turned and stomped away before either of them could say another word. As soon as she was gone they both let out the breath they'd been holding and breathed deeply.
